Specification of Letters Patent.

Patented Dec. 3, 1918.

Application filed April 24, 1917. Serial No. 164,241.

To all ywhom z't may concern.'

Be it known that I, AUGUST H. DEIKE, a citizen of the United States,residing at Takoma Park, Montgomery county, State of Maryland, haveinvented certain new and useful Improvements in Water-Closets, of whichthe following is a specification.

This invention relates to water closets and more particularly toautomatically operating Ventilated closets.

The objects of the invention are to pro- Vide a closet of this tvpe inwhich the flow of water to the flushing tank is controlled by the seat,either depression of the seat or raising the same opening the valvewhich permits the flow of water; to provide a pipe connecting the tankand bowl which shall act both as a flushing and Ventilating pipe; toprovide a flushing valve which shall also act as an overflow pine and aVentilating means; to provide an air-tight flushing tank and means forexhausting the air therefrom therebv producing a circulation of air andgases from the bowl to the tank; to provide an exceedingly simple andreliable means for operating the iushing valve: to provide means wherebythe fiushing valve is closed by the iow of water to the tank; to providea novel and exceedingly simple means for exhausting the air from thetank, which is actuated by the flow of water to the tank; and generallyto improve constructions of this type so that a minimum number of simpleparts are used, thereby, giving a structure which is dependable andoperates with a minimum amount of attention. 4

Other objects will be apparent from the description taken in connectionwith the drawings in which:

Figure 1 is a plan View of the apparatus, the top of the tank beingremoved to show the parts located therein;

Fig; 2 is a side elevation, the side of the tank being removed and theseat being shown in vdepressed position;

Fig. 3 isa front elevation, with the front of the tank removed andAshowing thefseat in depressed position.

The apparatus consists of a bowl 10 which may be-of the usual type -anda flushing tankll located above the bowl and connected thereto by ashort flushing pipe 12, which leads from the bottom of the tank to theside of the bowl near the top thereof. The bowl is provided with theusual seat 13 and when depressed is adapted to operate the plunger 14;to open the valve y15, which, through the pipe 16, is connected with awater supply. The outlet of the valve 15 is connected by means of aconduit 17 with the tank so that water may be supplied thereto. Thenormal position of the seat 13 is shown in dotted lines in Figs. 2 and3. It will thus be apparent that when the seat is depressed water willbe supplied to the iiushing tank. Means is also provided so that whenthe seat 13 is raised to a substantially vertical position, the valve 15will also be opened. For this purpose, one of the hinge members 18 ofthe seat is formed with a crank 19 which pivotally engages with a link20, the other end of which is connected by means of a pin 21 and slot 22with a lever 23 pivoted as at 21 on a bracket 25 which may be carried bythe conduit 17. The end of the lever 23 opposite the pin 21 is formedwith a voke 2G and the arms of this yoke are each formed with slots 27which are adapted to receive pins 28 carried by the plunger 14. A spring29` which may be interposed between the pin 21 and the conduit 17 actsto raise the plunger 14 and hold the Valve 15 closed. It will beapparent that when the seat 13 is raised to a substantially verticalposition, through the crank 19 and link 20, the lever 23 will be rockedto thereby depress the plunger 14 and open the valve 15, thus permittingwater to fiow to the tank.

All of the apparatus for Ventilating the bowl and actuating the flushingvalve is located within the tank, which may be of any desiredconstruction, the only requirement being that it shall besubstantiallyair-tight. As clearly shown in the drawings; the conduit 17extends through the bottom of the tank and through a bracket fitting'v8O which is held rigid in any desired manner. This bracket 30 has ashort section 31 of the conduit cxtendingvertically therefrom andsubstantially parallel therewith a standard which consists of a Verticalmember having a horizontally arranged arm 33 at the upper end thereoffor a purpose presently to be described. Arranged near the end andslightly below the said arm 33 is the discharge section 31 of theconduit, which may be provided with the spray nozzle 35 through whichthe water is discharged. The discharge section 34 is arranged at anangle to the section 31 of the conduit and these two sections may beconnected by means of a section 36 which is yieldably secured to saidsections 31 and 34. For this purpose the connecting section may be apiece of flexible tubing, although any other suitable means may be used,the only requirement being that the said connecting section 36 be joinedto the sections 31 and 34 so that the section 34 may be permitted tomove under the force of reaction due to the iiow of the water throughthe bend 37 in said connecting section. It is therefore obvious thatthis connecting section might consist of a rigid tube having the bend 37therein and connected at its ends with the sections 31 and 34 byuniversal joints.

The discharge section 34 of the conduit is provided with a pair ofoppositely extending pins or trunnions'38 and 39 each of which ispivotally connected to a pair of links 40 and 41, which are arranged toform a toggle joint. For this purpose the links 40 at their upper endsare pivotally carried by pins 42 secured to the arm 33 previouslydescribed. The links 41 extend downwardly from the trunnions 33 and 39and at their lower ends are pivotally secured at 43 to a verticallyarranged tubulai member 44 which constitutes the flushing valve. Thusthe flushing valve 44 is of sufficient height so that it forms anover-flow pipe and at its lower end is adapted to seat against avfitting45 in the bottoni of the tank to thereby close the opening to theiushing pipe 12 to thereby permit the tank tobe filled with water to aheight equal to the height of the member 44. The flushing valve ismounted for movement away and toward the bottom of the tank bv meansofptwo parallel links, one arranged at the top of the valve and theother near the bottom thereof. As clearly shown in the draw ings, theupper link consists of a yoke member 46, the two arms 47 and 48 of whichare arranged on opposite sides of the valve 44, and the standard 32. Theends of these arms are connected to the valve 44 by means of the pins 43and near the base of the fork are pivotally mounted on the standard 32by means of the brackets 49. The arms 47 and 48 are slidable through thebrackets 49 and are adapted to be secured in adjusted position by theset screws 50. The stem 51 of the yoke has a weight 52 slidably mountedthereon and adapted to be secured in any adjusted position by a setscrew 53. The link at the lower end of the valve is arranged similar tothe link just described, except that it is not necessary to provide thesame with a weight similar to the weight 52. As shown, this lowerlink'has the side arms 54 which at onevend are connected by means ofpins 55 with the valve and at the other end are pivotally connected tothe standard 32 by the brackets 56 through which the arms are slidableand adapted to be secured in adjusted position by the set screws 57. Thearrangement of the parts just described is such that the weight 52 isjust suflicient to throw the toggle joints into the position indicatedby the dotted -lines and thereby raise the flushing valve 4.4 off itsseat at the bottom of the tank. When water flows through the supplconduit theI force of reaction due to the de ection of the streambecause of the bend 37 causes the discharge section 34 with its nozzle35 to move toward the left as viewed in Fig. 3, thereby shifting thetoggle joint from. the dotted line to the full line position and -thusforcing the flushing valve to its seat from the top of a hollowcylindrical member 59, the interior of which constitutes a separatingchamber. The top of this cylindrical member is closed and the bottoniedge is formed with a series of feet 60, thereby forming between thesame a series of notches 61 to permit water to pass from the interior of the member 59 into the tank. At the rear side and near the top, themember 59 is pro vided with an air discharge passage 62. In order tosecure the cylindrical member 59 in position, a ring 63 may be arrangedaround the same near the base thereof with one end extending through andsecured to the rear wall of the tank. In the operation of thisVentilating means the water discharged through the nozzle 35 exercisesan aspirating action, drawinoa air along with it through the nipple 58and into the separating chamber, where the air passes `out through thedischarge opening 62 and the water falls to the bottom and passesthrough the opening 61 to fill the tank. Of course, this aspiratingaction of what may be termed the gas or air ejector tends to exhaust theair from the tank and this reduction of pressure within the tank causesair and gases to be drawn through the flushing pipe 12 and flushingvalve 44 intothe tank. Thus air and gases are continually withdrawn fromthe bowl.

In the operation of the apparatus when the seat 13 is either depressedor raised the valve 15 is opened, thereby permitting water to besupplied to the tank. This flow of the supply water causes the flushingvalve to be closed andalso operates the gas or air iis ist

ejector to Ventilate the bowl. When the seat is permitted to assume itsnormal positlon the weight 52 raises the flushing valve 44, therebypermittin water to iow to the bowl to flush it out an as the movement ofthe seat to its normal position closes the water supply valve 15 the asor air ejector no longer operates and t e Ventilating action thereforeceases.

Having thus described the invention, what is claimed and desired to besecured by Letters Patent is:

1. In a Ventilating closet construction, a substantially air-tight tankhaving a gas outlet, a bowl, a single pipe connecting the tank and bowl,means for eEecting a discharge of gas from said tank, and a flushingValve for said pipe formed with a passage therethrou h forming anextension of the pipe, where y the iiushing Valve also acts as anoverflow and Ventilating means.
